Washing your car might seem straightforward, but experts from Which? warn that common mistakes—like cleaning in direct sunlight or using harsh products—can lead to scratches, swirl marks, and damaged paint. Here’s how to do it right.

1. Avoid Washing in Direct Sunlight
Sunny days may seem ideal, but they leave water spots as heat speeds up evaporation. Soap can also dry before rinsing, making it harder to clean. Opt for a shaded, cooler time of day. After washing, park away from trees or dusty areas to protect your car from sap, bird droppings, or debris.

2. Skip Automatic Car Washes

While convenient, automatic car washes often harbor grit from previous users, causing scratches or swirl marks. Self-service brushes are equally risky. Instead, use a pressure washer, two buckets (one for soap, one for rinsing), a wash mitt, and car shampoo. The “two-bucket method” reduces dirt transfer—rinse your mitt in the water bucket before reloading soap.

3. Never Use Dish Soap or Kitchen Sponges
Dish soap strips protective wax and degrades paint over time, while abrasive sponges scratch surfaces. Invest in a soft wash mitt, pH-neutral car shampoo, and microfibre towels.

4. Remove Bird Droppings Gently
Scraping dried droppings risks scratches. Instead, soak a cloth in hot water, lay it over the spot to soften, then wipe gently. Keep bird poo wipes handy for quick cleanups.

5. Polish and Wax for Long-Term Protection
Polishing removes minor imperfections, while wax adds a protective, glossy layer. Apply polish first (if needed), then wax. Though time-consuming, this combo preserves your car’s shine and shields against UV rays and contaminants.

6. Avoid “Cockpit Shine” Products
Shiny interior sprays often leave greasy residues, creating hazards on steering wheels or pedals. Instead, vacuum dust and wipe surfaces with a damp cloth. For stubborn stains, use a mild detergent.

Final Checklist

• Wash in shade with proper tools.
• Hand-wash using two buckets.
• Use car-specific shampoo and soft mitts.
• Prioritize gentle cleaning for bird droppings.
• Polish and wax periodically.
• Keep interiors clean with non-greasy methods.
